Tyler, leader of a rising in Ottawa? (3)
I believe the answer is:
wat
'tyler leader' is the definition.
The definition suggests a singular noun which matches the answer.
'of a rising in ottawa?' is the wordplay.
'a rising' is a reversal indicator (in a down clue, letters go up).
'of' indicates the answer is hidden within the clue.
'taw' is hidden within 'in ottawa'.
'taw' written backwards gives 'WAT'.
Can you help me to learn more?
(Other definitions for wat that I've seen before include "Buddhist temple" , "Rebel" , "having had a wee drap too much?" .)
